What is a Transistor
A transistor is a solid state semiconductor device which can be used for numerous purposes including signal modulation, signal amplification, voltage stabilization, and many other applications.

Transistors act like a variable valve which, based on its input current (BJT) or input voltage (FET), allow a precise amount of current to flow through it ....etc

ABSTRACT
SPECT, the acronym for Single Photon Emission Computed
Tomography, is a nuclear medicine imaging modality, giving information
about a patient s specific organ or body system. The patient is
injected with a radiopharmaceutical, which will emit Gamma rays. The
radio activity is collected by an instrument called gamma camera and
the image is reconstructed. SPECT is used to make three dimensional
images of the heart, to perform brain studies and for skeletal

SPECT, the acronym for Single Photon Emission Computed Tomography, is a nuclear medicine imaging modality, giving information about a patient?s specific organ or body system. The patient is injected with a radiopharmaceutical, which will emit Gamma rays. The radio activity is collected by an instrument called gamma camera and the image is reconstructed. SPECT is used to make three dimensional images of the heart, to perform brain studies and for skeletal scintigraphy. It is reasonable to speculate about a constant by perhaps a slower rate of in ....etc

1. INTRODUCTION

Emission Computed Tomography is a technique where by multi cross sectional images of tissue function can be produced , thus removing the effect of overlying and underlying activity. The technique of ECT is generally considered as two separate modalities. SINGLE PHOTON Emission Computed Tomography involves the use single gamma ray emitted per nuclear disintegration. Positron Emission Tomography makes use of radio isotopes such as gallium-68, when two gamma rays each of 511KeV, are emitted simultaneously where a positron from ....etc

Single-Electron Transistor (SET) Process and Device Simulation Using SYSNOPSYS TCAD Tools
Abstract:
Simulation of semiconductor device fabrication and operation is important to the design and manufacture of integrated circuits because it provides insights into complex phenomena that cannot obtained through experimentation or simple analytic models. Process and device simulation is commonly using for the design of new very large scale integration (VLSI) devices and processes. Simulation programs serves as exploratory tools in or ....etc

ABSTRACT
The shotgun marriage of chemistry and engineering called Nanotechnology is ushering in the era of self-replicating machinery and self-assembling consumer goods made from raw atoms. Utilizing the well understood chemical properties of atoms & molecules, nanotechnology proposes the construction of novel molecular devices possessing extraordinary properties. The single electron transistor or SET is a new type of switching device that uses controlled electron tunneling to amplify current.
By using the Electr ....etc

Definition

With the proliferation of portable electronic devices, power efficient data transmission has become increasingly important. For serial data transfer, universal asynchronous receiver / transmitter (UART) circuits are often implemented because of their inherent design simplicity and application specific versatility. Components such as laptop keyboards, palm pilot organizers and modems are few examples of devices that employ UART circuits. In this work, design and analysis of a robust UART architecture has been carried out to minimiz ....etc
